Find (if possible) the trig function of the quadrant angle.
sec 3pi/2

well, it is .... 270 degrees....so cosine of 0 is 1, cosine 90 is 0, cosine 180 is 1, cosine 270 is o, so sec = 1/cosine= undetermined...

At 3π/2, a rotating arm ends up on the negative yaxis (270°)
If we consider a unit circle, then the terminal arm ends up at (0,1), that is,
x=0, y = 1, r = 1
cos (3π/2) = 0/1 = 0
so sec(3π/2) = 1/cos(3π/2) = 1/0
which would be undefined.
